$[15$p$]$ Mandatory. All potential user input errors$/$mistakes MUST be processed with corresponding messages $($you can do this with JavaScript or other HTML functions$).$ Make sure you have at least $50$ valid contacts in the file. Please make sure you comment and indent your code. A $10$ points penalty will be assessed if comments are not available. While you are NOT allowed to cut$/$paste JavaScript code from the web, you may study code examples available on the web, as well as the ones discussed in our discussion forum. $($HINT: HTML $5$ also provides ways to check for user input errors$).$
